Decomposing delta, theta, and alpha time-frequency ERP activity from a visual oddball task using PCA.


OBJECTIVE Time-frequency (TF) analysis has become an important tool for assessing electrical and magnetic brain activity from event-related paradigms. In electrical potential data, theta and delta activities have been shown to underlie P300 activity, and alpha has been shown to be inhibited during P300 activity. Measures of delta, theta, and alpha activity… (More)
